He did not use a shift register chip. <br />Of course, there is no code supplied, which is frustrating, because I am not a computer guy.<br />He had to use something like what you illustrated above, but that is above my head.<br />Please help me suggest the necessary modification to input a 5 x 6 matrix. I created the appropriate diode matrix already on a small circuit board, so that part is ready. I am expecting my Arduino Uno R3 USB Microcontroller (unprogrammed) any day.<br />Thanks in advance for your guidance.Andrew Ernyeshttps://www.blogger.com/profile/17988894419851310100noreply@blogger.comtag:blogger.com,1999:blog-7747329480549483400.post-41681390344508182662017-05-16T18:41:42.897-07:002017-05-16T18:41:42.897-07:00hello great project.

I have the exact same Casio keyboard you used but when I connect a multimeter in diode check mode across two of the pins and sweep the keys I don&#39;t get anything. I would just copy your schematic but this is an excersise in learning as much as anything else. Is there something odd about these rubber dome switches I should know or am I missing something else? The keayboard is still completely intact currently, I haven&#39;t removed the keyboard from the main board since i&#39;d like to leave the main board intact and just add MIDI as well. <br /><br />Thanks<br />JakeJake Charmanhttps://www.blogger.com/profile/06026765352320662738noreply@blogger.comtag:blogger.com,1999:blog-7747329480549483400.post-81776163095503958302016-08-21T17:44:39.556-07:002016-08-21T17:44:39.556-07:00OK!!

My Korg Microkey 37 has kicked the bucket. Is it possible to do something like this, but using USB as the communication medium into my PC? I feel as though I am going to have to gather resources from a few different DIY projects and see if I can apply them to my own dilemma. I&#39;m just really glad I&#39;m finally knocking the dust off of that old Arduino Uno I&#39;ve had for like 5 years!

I succesfully made it, thanks a lot and god bless you.<br />However im able to play each key with exactly the same not but i can play #chords with it. Also when i press adjacent keys the first key&#39;s (from left) note is played and the other is ignored at many places in my keyboard. :( After working so hard i didnt expected this. Well i used keyboard with 54 keys and my scanned matrix was 8col*7rows. <br />Please its very urgent<br />Thankyou for your help. <br />My email : lovesk689@gmail.comSkRokz _stayTunehttps://www.blogger.com/profile/02705897801583093201noreply@blogger.comtag:blogger.com,1999:blog-7747329480549483400.post-35416163796307481442016-04-13T09:52:22.521-07:002016-04-13T09:52:22.521-07:00do you have schematic for this project?
